Session control with SSM
The OpenTV Platform uses the Secure Session Management (SSM) service, part of NAGRAVISION's Security Services Platform (SSP), to limit the number of concurrent streams consumed by client apps.
A client app attempts to set up a session for each new playback session, and SSM enforces this limit. While playing content, the app must send keep-alive requests at regular intervals. If it fails to do so, SSM will end the session and playback will stop.
After playback, the app must tear down the session. This allows SSM to decrement the session count.
SSM also offers APIs for the operator to tear down existing sessions on a per-account or per-device basis.
The following use cases are supported:
To integrate against SSM, you will need to refer to the SSM API documentation. This is part of the SSP portal – to get access, please contact your NAGRAVISION representative.
